1:00pm PST (2100 GMT) Duration 4 hours: ESX hardware upgrade. We’ll be upgrading the production ESX cluster from old dual CPU HP DL385 servers to our standard 8-core/32GB RAM HP BL460 platform. Since this upgrade involves switching CPU platforms (AMD to Intel), it requires each VM to be shutdown, migrated and powered up. Each VM’s downtime will be not unlike a normal reboot.The following list includes notable VMs & services that will be briefly affected:

Please let me know if you have any reason why we should not proceed with this planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

Feel free to comment directly if you see issues past the planned downtime.

IIUC, IRC users connected via sand.mozilla.org (San Jose, Calif.) will be disconnected during the “reboot” but gravel.mozilla.org (Amsterdam, The Netherlands) will hold the fort and “only” experience a netsplit?
